The present study tried to use diffusion tensor imaging (DTI) to delineate the possible white matter track for the cognitive processes on normal healthy subjects. The results of previous fMRI study were used to guide ROI selection for tractography. In order to increase the reliability of tracking results, all the track data were then transformed to standard space to make probability maps. Finally, we performed correlation test to test whether the tracks play important roles in the information processing of the cognitive function.
